Melody. The melody projects a third-progression, Anne’s typical motive, over its full length. That large third-progression, F-E♭-D, is elaborated with smaller third-progressions, D-F, C-E♭, and B♭-D. The same melodic framework, F-E♭-D, underpins the melody in measures 16–19, 25–28, and 29–32, but the effect here, within a shimmering, rapturous B♭ major, is utterly different.
